Description

hEFIM S.A.

Performing the transmission of signals to one Magnetic induction projectile detonator

The present invention relates to an apparatus made by magnetic induction, when controlling a bullet detonator, for the transmission of an energetic signal and the signals according to the data regarding the mode of operation and / or the delay the ignition is used, this device having a transmitting part outside and a receiving part inside the igniter.

I'ian already knows devices in which the transmission of the Signals is achieved by means of a single magnetic circuit,>: obei the various signals superimposed during the broadcast and during g can be sieved or separated.

The purpose of the invention is to manufacture the device more economically, which is possible because their mechanical components are smaller and their receiving circuit less electronic Components required. For this purpose, the inventive Device characterized in that it comprises at least two magnetic control circuits which transmit an energetic Signals and / or data corresponding signals guaranteed.

The accompanying drawing shows schematically and by way of example two Embodiments of the device according to the invention. Show it:

1 shows an axial section of the first embodiment,

FIG. 2 is a cross-section on the line A-A of that shown in FIG Contraption,

Pin cross-section of the second run.

In Fig. 1, a floor 1 was hurried, in which a first rapnet core 2 is installed, on which a back / ^T 3 nits, which serves to receive an energetic signal, which see through induction of a magnetic core 4 is generated, on which a winding 5 sits.

In the bullet tip 1 there is also a disordered magnetic core 6, on which a certain number of windings sit, as shown in FIG . Each prong IL , 11 or 12 carrying a winding 7, 8 or 9 forms a magnetic circuit with the adjacent prong 11, 14 or 15 and a magnetic core 16, 17 or 18 located outside the igniter. These magnetic cores 16, 17 and 18 each have a winding 19 »20 or 21, which serves as a data transmitter. Any magnetic circuit formed in this way can be used for data transmission by induction.

One of these magnetic control circuits can be used, for example, to transmit serve to delay the ignition. A second magnetic control circuit can be used to determine the delay of the Muzzle security and the third can be used to change other parameters of the mode of operation of the detonator. Such a one The device thus allows the energy required by the detonator after the projectile has been fired and the various information signals to be transferred individually.

This arrangement is. particularly favorable because it enables automated control, e.g. by means of a data processing system. It also enables the information to be reread, too their review and possible modification.

Fig. 3 shows a variant in which four magnetic

In both of the embodiments explained, it is of course necessary to provide a gown to adjust the angle of the transmitter part in relation to the catch part, so that the differentiated elements work Correctly in relation to the assigned receiving λioklur, if necessary-r. 2Li are KO "imen.

in the-.' The inventive device can be used just as well with projectiles in throwers as with proximity detonators with time or opening, with or without a twist effect.
